, INTRODUCTIELES
FUNCTIE
Propulsie : voortstuwen v voedsel v mond naar anus (peristaltiek)
Vertering v voeding
- Zure pH → maag
- Enzymes → speekselklieren, maag, pancreas
Absorptie (water & voedingstoffen) → dundarm
Detoxificatie (opgenomen voedingsstoffen) → lever
Secretie (interne & externe giftige substanties) → colon, lever
Afweer (immuunsysteem) → GALT : want alles wat in maag = buitenwereld → moeten ons kunnen
verdedigen
OPBOUW (MACRO- & MICROSCOPIE)
4 lagen:
Mucosa
- Epitheel (+ basale membraan)
- Lamina propria (losmazig bindweefsel, capillairen, GALT, zenuwvezels)
- Muscularis mucosae
Submucosa
- Losmazig bindweefsel
- Submucosale klieren
